Every Hot Water System We Service Across Adelaide
Different hot water systems fail in different ways. Gas continuous flow throws error codes. Electric storage tanks lose their element. Solar systems fail at the booster before the panels. Heat pumps are usually a fan or thermistor issue. We diagnose the actual fault before quoting – and price the repair honestly against the cost of replacement.

Should You Repair or Replace Your Hot Water System? Honest Guide for Adelaide Homes
Not every hot water problem needs a new system. Not every system that fails is worth repairing. Here is how our licensed Adelaide plumbers assess the honest answer at your property – based on age, symptom, & repair cost against replacement value.
| System Age | Symptom | What We Usually Recommend | Typical Cost |
|---|---|---|---|
| Under 5 years | Element or thermostat failure | Repair – part is cheap, system life ahead | $250-$450 |
| 5-8 years | Element failure, first time | Repair – still economic | $250-$450 |
| 5-8 years | Tank leaking | Replace – leaks do not repair | $1,800-$3,500 |
| 8-12 years | Element failure, second time | Replace – money better spent on new | $1,800-$3,500 |
| 8-12 years | Slow recovery, running out | Assess – often replace with correct size | Quote after check |
| 12+ years | Any major fault | Replace – past economic life | $1,800-$3,500 |
| Any age – gas system | Error code Rinnai, Bosch | Diagnose first – most codes are fixable | $300-$650 |
| Any age – solar | Booster failure | Repair booster – panels usually fine | $400-$800 |
